JOHN LEE COX, OF KENDRA, ONTARIO, CANADA.

OIL-STOVE.

To'all whom-it may concern Be it known that I, JOHN LEE COX, a subjectof the King of Great Britain, and a resident of the town of Kenora, inthe Province of Ontario, Canada, have invented certain new and usefulImprovements in Oil- Stoves, of which the following is thespecification.

The invention relates to improvements in oil stoves and the object ofthe invention is to provide a stove of the above class especiallyadapted for household useand which is arranged so that it can beinserted in the lid opening of an ordinary stove and used to heat thestove.-

A further object of the invention is to provide an oil stove which willproduce a very intense heat for the amount of fuel consumed, and a stillfurther object is to construct an inexpensive, easily assembled stovehaving few parts and arranged such that it can be readily opened andcleaned.

With the above objects in view the invention consists essentially in apan provided with a hinged top and forming a combustion chamber, the panhaving an opening in the side thereof, a feed pipe connected to the panand entering the same and having the inner end coiled withinthecombustion chamber and terminating ina jet, air ducts opening to thecombustion chamber at a point adjoining the jet and an asbestos or othersimilar absorbent noninflammable material contained in the base of thepan, the parts being arranged and constructed as hereinafter moreparticularly described and later pointed out in the appended claims.

Figure 1 represents a side view of the device as it appears inserted inthe lid opening of the ordinary coal or wood stove. Fig. 2 represents aplan view of the oil stove. Fig. 3 represents a vertical sectional viewcentrally through the same, parts being shown in side elevation. Fig. 4represents a horizontal sectional view through the oil stove, thesection being taken in the plane denoted by the line XX' Fig. 3. Fig. 5represents a vertical sectional view through the lid, the section beingtaken in the plane denoted by the line Y-.Y' Fig. 2. Fig. 6 represents adetailed vertical sectional View through a portion of the lid and pan,the section being taken in the plane denoted by the line Z-Z Fig. 2.

Specification of Letters Patent.

Application filed April 6, 1914.

Patented July as, 1914.

Serial No. 830,029.

In the drawing like characters of reference indicate corresponding partsin each figure.

1 represents a pan preferably of a cylindrical form provided with anout-turned top flange 2 and having an opening3 formed in the sidethereof. The pan is preferably cast from iron and is formed in castingwith a cross strip l to which I have attached by suitable hinges 5, thecover or lid 6 arranged to shut down on the pan and inclose thecombustion chamber 7 The lid is formed with a central opening 8 whichcommunicates in the present instance withfour similar ducts or passages9, the central opening and ducts being preferably cast in the lid.

10 is a feed pipe leading from an oil supe ply tank 11 and securedpermanently to the cross strip 4 through which it passes, the lower endof the pipe being formed into a coil 12 which terminates in a nipple orburner 13 located just below the opening 8 and slightly to the side ofthe center.

thereof. The jet is deflected slightly downwardly anddirected toward theopening 3.

14 is a valve controlling the supply of oil through the pipe.

15 is an asbestos or other such absorbent and non-inflammable materiallocated in the base of the pan beneath the coil..

16 and 17 are lugs cast on the pan and located slightly below the flange2.

I have not shown any means for locking the lid closed but any suitabledevice could be used for this purpose if desired;

The oil stove is specially constructed to be inserted within the lidopening of the ordinary wood or coal stove. The top of such a stove isindicated in Fig. 1 by the reference numeral 18. Such stoves areequipped with lid openings 19presenting at their sides a ledge 20 onwhich the lid rests. The pan of my stove is arranged so that when thelid of the ordinary wood or coal stove is removed the pan can beinserted in the lid opening with the flange 2 resting on the ledge 20and the lugs 16 and 17 projecting beneath the ledge. The lugs thenprevent any possibility of the oil stove being upset, as any upendingaction due to the weight of the tank 11 is offset by the lugs.

To light the oil stove when installed as shown in Fig. 1 one has simplyto raise the lid 6, pour a small quantity of oil onto the asbestos pad15 and then ignite the oil, the lid being afterward closed. The chamber7 becomes hot and accordingly heats the coil. Then the coil has becomemore or less heated the needle valve is opened and the oil flows downfrom the tank 11 through the pipe 10 to the coil where it is heated andis" vaporized and ignites of itself the instant it escapes through thejet. Combustion is supported by the air admitted through the ducts 9 andthe opening 8.

I wish to draw particular attention to the fact that the air supplied tosupport combustion is heated in the ducts prior to entering thecombustion chamber. It is obvious that the lid will become heated at theonset and will remain intensely hot during the time the stove is inuse.

The flame from the burner or jet is deflected down by the incoming airwith the result that it plays on the coil and heats the same to anintense heat thereby insuring the positive vaporizing of the oil passingthrough the coil. I might remark that when the device is in use a tongueof flame proj ects through the opening 3 and plays across practicallythe full width of the ordinary coal stove and also that when my oilstove is used in the ordinary coal or wood stove all the air drafts ofthe stove require to be closed.

Vhat I claim as my invention is;

1. An oil stove comprising a pan having an opening in the side thereof,a hinged cover normally closing the pan and provided with a centrallylocated air opening and a coil contained within the pan having one endcommunicating with a supply tank and the opposite end thereof formedinto a burner, said burner being directed toward the opening in the sideof the pan and located adjoining the opening in the top of the pan, asand for the purpose specified.

2. An oil stove comprising a pan having an opening in the side thereof,a hinged cover normally closing the pan, said cover being provided witha centrally located air opening communicating with air inlet ductsformed in the cover and a coil contained within the pan and having oneend communicating with a sup-ply tank and the opposite end formed into aburner directed toward the opening in the side of the pan and located ata point adjoining the opening in the cover, as and for the purposespecified.

3. An oil stove comprising a cylindrical pan fitted with a side openingand a top outstanding fiange, a hinged cover normally closing the top ofthe pan and provided with a centrally disposed air opening communieeating with a plurality of radiating air ducts formed in the cover, acoil contained within the pan and having one end communicating with asupply tank and the opposite end formed into a burner, the said burnerbeing directed toward the opening in the side of the pan and beinglocated directly beneath the air inlet opening in the cover and anoninflamma-ble absorbent material contained in the bottom of the panbeneath the coil, as and for the purpose specified.

Signed at l/Vinnipeg this 27th day of February 1914;.
